Comparing updated array from two consecutive iterations

Hi, I need to create a while loop for a for loop which iterates until the difference between the array c of the current iteration and the array c of the previous iteration is small. Any suggestions on how I could save the updated array for each iteration and then compare the 2 consecutive iterations?

Like this:
prv = 0; % pick first previous value
for ...
new = ...
...compare prv & new, do whatever
prv = new;
end

Use a while loop that is sure to make at least two trips through.
old = all NaNs so as to surely fail 1st test
b = false;
while ~b
new = ...
b = old and new difference is sufficiently small
old = new;
end
